  • Rudder device
    Patent number: 5671691
    Abstract: A rudder device for water-going craft or aircraft, where there is provided in the vessel a cavity (21) which is open to the outside of the vessel. In the cavity there is provided a body (2) which can rotate about an axis (3), which extends in the cavity (21) and out through the opening (22). The body (2) supports a rudder blade (7) which is fixed or movable in relation to the body (2) substantially in the direction of the axis of rotation (3) through the opening (22) and arranged to be secured by the body (2) after having been moved. The vessel is steered by turning the body (2) by the vessel's steering device.

  • Cooling water inlet and method of fabricating a cooling water inlet member
    Patent number: 5607333
    Abstract: A cooling water intake (1) is constructed as an integral body from a composite material, having a duct (2) running from a first opening (3), adapted to face toward the sea, and to a second opening (4), where the cooling water intake may be connected to the cooling water system of a motor. The duct (2) is curved inward and toward the stern, and the duct cross section is flattened near the first opening, which faces to the sea. Toward the second opening (4) the cross section of the duct progresses into a conventional circular cross section. The invention also relates to a method for fabricating a cooling water intake body.

  • Device for the production of oil/petroleum products at sea
    Patent number: 5505151
    Abstract: A vessel for use in the refinement or production of oil/petroleum products at sea at a location at a distance from the coast is designed as a ship (1) of the lash type, in which there are integrated a number of barges (2) which can be removed from the ship's hull and used as independent transport vessels for the transport of products to and from shore. In the ship there is integrated manufacturing or production equipment in a unit (4). This unit (4) can also be provided in a barge which is part of the lash construction. The manufacturing equipment in the unit (4) is preferably positioned close to the ship's means of propulsion and control. In the ship's construction between the barges and the production equipment (2, 4), there are integtrated transport systems for the products obtained.
